In @EATSSU/App/Sources/Data/LocalDB/AccountStorage.swift:
- Line 13: Update TokenStore.clear() and AccountStorage.reset() to return and
propagate KeychainHelper.delete failures instead of clearing only the cache;
update callers to complete logout only after token deletion succeeds.
In @EATSSU/App/Sources/Data/LocalDB/TokenStore.swift:
- Around line 47-48: Update the token-saving method containing
`cachedAccessToken` and `cachedRefreshToken` so that if either save fails, it
deletes both Keychain entries, clears both cached tokens to empty strings, and
returns failure. Only update the cache with the new token pair and return
success when both saves succeed.
In @EATSSU/App/Sources/Data/Network/Foundation/TokenRefresher.swift:
- Line 42: Handle both TokenStore.save call sites: in TokenRefresher, throw an
error when saving fails and propagate that failure to waiting requests; in
LoginViewController, return the save result to the caller and stop user-info
creation and profile lookup when saving fails. Update
EATSSU/App/Sources/Data/Network/Foundation/TokenRefresher.swift at line 42 and
EATSSU/App/Sources/Presentation/Auth/ViewController/LoginViewController.swift at
line 146.
- Line 42: TokenRefresher의 refreshIfNeeded()에서 재발급 요청 세대를 기록하고, 로그아웃
시(AccountStorage.reset() 경로) 인증 세대를 무효화하세요. performReissuance() 완료 후
TokenStore.save 직전에 요청 세대와 현재 세대가 같은지 확인해, 로그아웃으로 세대가 바뀐 경우 응답 토큰을 저장하지 않도록 하세요.
In
@EATSSU/App/Sources/Presentation/Map/ViewController/MainMapViewController+Network.swift:
- Line 198: refreshPartnershipTab의 성공 콜백에서 화면 상태와
UserInfoManager.shared.updateDepartment를 갱신하기 전에 현재 요청 세대가 최신인지 확인하세요. 오래된 응답은
학과 정보를 저장하거나 화면 상태를 변경하지 않도록 하세요.

@EATSSU/App/Sources/Data/Network/Foundation/TokenRefresher.swift:
- Around line 51-52: Update the token persistence failure path in TokenRefresher
so a failed TokenStore.save does not become sessionExpired or trigger account
reset. Preserve the existing valid tokens on save failure and propagate a
distinct storage error to the caller.
- Line 44: In the TokenRefresher flow around performReissuance(), capture
TokenStore.refreshToken before the request and, in the error path, compare it
with the current token. If it changed, propagate TokenRefresherError.discarded
to waiting continuations and the caller; otherwise propagate the original error.
- Line 47: Make the refresh-token comparison and token save in TokenRefresher
atomic by using a TokenStore operation that checks the expected refresh token
and saves the new tokens under the same lock. Preserve the existing error
behavior: discard on mismatch and report session expiration if saving fails.

#465 (1단계 — 2단계 Realm 제거까지 이슈 유지)
💡작업 내용
Realm을 걷어내기 위한 1단계(마이그레이션 버전) 입니다. 로그인 토큰은 Keychain, 사용자 정보는 UserDefaults로 옮기고, 업데이트 사용자의 기존 Realm 데이터를 첫 실행에 한 번 이전합니다. 이번 버전은 기존 파일을 읽어야 해서 Realm 의존성은 남아 있고, 다음 버전에서 Realm을 제거합니다.
왜
1. 새 저장소
TokenStore: Keychain(AfterFirstUnlockThisDeviceOnly— 백업·기기 이전으로 복원되지 않음). 요청마다 읽히므로 메모리 캐시 + 잠금. 읽기 실패(첫 잠금 해제 전)는 캐시하지 않음UserInfo: RealmObject→Codable구조체,UserInfoManager가 UserDefaults에 JSON으로 저장AccountStorage.reset(): 로그아웃·탈퇴·세션 만료 시 토큰·프로필·찜 상태 정리 (기존resetDB()대체)KeychainHelper에 접근 시점 지정과 삭제 추가 (기존 호출부 동작은 그대로)2. 기존 데이터 이전 (
LocalStorageMigrator)default.realm이 있으면(업데이트 사용자) 토큰·프로필을 옮기고 Realm 파일 삭제_realmObjectName으로 테이블명Token/UserInfo유지)로 읽음3. 호출부
RealmService.shared.getToken()등 →TokenStore,UserInfoManager.update…(for:)→ 대상 인자 없이 호출검증
[LocalStorageMigrator] 이전 완료 (토큰: true, 사용자 정보: true), 로그인 유지된 채 홈 진입, UserDefaults 프로필 값 일치,default.realm삭제 확인💬리뷰 요구사항(선택)
default.realm.lock파일 하나는 Realm이 지우지 않아 남습니다(약 1KB). 2단계에서 정리합니다.Summary by CodeRabbit
